Specification of Letters Patent.

To @ZZ whom, it may concern:

Be it known that we, CHARLES J. CALEY and HENRY G. VOIGHT, citizens of the United States, residing at New Britain, Hartford county, Stateof Connecticut, have inventedcertain new and useful Improvements in Locks, of which the following is a full, clear, and exact description.

Our invention relates to locks and latches,

and particularly to a lock which we term a' tion whereby the latch is operated by knobs arranged on the outer and inner sides of the door and whereby the mechanism may be dogged or locked against operation whenever desired. There are also features of construction whereby the escutcheon-plates, which carry the aforesaid knobs, may be moved' to and fro, whereby the lock may be applied to doors of different thicknesses and without disturbing the operative relation of the parts of the lock mechanism.

In thedrawings, Figure 1 is a horizontal section of a portion of a door, showing our lock in position and partly in horizontal section and partly in elevation. Fig. 2 is an elevation of the inside of the latch-slide-carrying plate and the associated parts. Fig. 3 is 1 a longitudinal section of the rear end of the part shown in Fig. 2. Fig. 4 is an elevation of a detail of construction.

A A are two independent escutcheonplates arranged to bear on opposite sides of a door and clamped securely thereon by means of screws R R passed through one plate and taking into bosses R R in the opposite plate. The plate A is hollowed out on its inner surface to receive a latch-slide B.

C is an end plate, preferably formed integrally with the plate A and arranged to overstand the edge of the door. This end plate C may be reinforced by side ribs C C.

D is a latch moving through the end plate C, while D is a latch-slide connection arranged at the rear of the latchV D.

E is an easy-spring carried by the end plate and arranged to press the latch D outwardly.

The latch-slide B is hooked at its end, as at B B, to engage with a coupling-pin D2 on the latch-slide connection D.

E is aheavy spring carried by the plate A and arranged to press against the rear end of the latch-slide, or a part thereof, to advance the same.

Mounted on the latcheslide B is a secondary dogging-slide F, which slide is capable of being reciprocated on the slide B in a direction transverse to the line of movement of the latter. The dogging-slide of course reciprocates to and fro with the latter.

F F are downwardly-turned horns on slide F, while G Gare stops on the plateA ad jacent to said horns.' When the horns F F stand in front of the slide B, the slide B cannot be retracted. This position is shown in solid lines, Fig. 2. If the Vdogging-slide F is moved to the position indicated in dotted lines, Fig. 2, the stops G G will stand out of the path of the horns F F and consequently the slide B may then be retracted.

To operate the slide F to throw it from its locking position, and vice versa, we provide key-actuated mechanism, which in the preferred form comprises two cylinder-locks, one of said locks being located in each of the knobs H H, as indicated in dotted lines.

H2 H3 are the knob-Shanks of knobs H H respectively. The knobs H H are independent and are each carried by the plates A A', respectively, in such a manner that they will move to and fro therewith.

The hubs of the cylinder-locks carry spindles I I which in turn carry at their adj acent ends the roll-backs J J, respectively. To insure proper alinement of these rollbacks, we may provide a centering-pin K, the ends of said pin being let into the ends of the spindles I I. These spindles I I are independently rotatable, and either one may be turned by means of a ro er key introduced into either lock in t e rnob H or H. By turning either spindle I or I the roll-back carried thereby may be rotated so as to engage with a suitable shoulderfor example,

IOO

its operative positions.

formed by the notch L-on the dogging-slide F, whereby said dogging-slide will 'be shi'l'ted in such a manner that its horns F F will stand infront of the stops G G or to one side thereof.

M is a roll -back carried directly by the shank H2 of the knob H and engaging with the slide B.

The knobs are connected by a novel coupling, the arrangement being such that the knobs may be moved to and fro when the plates A A are moved to and fro without disconnecting said knobs or the associated parts from the mechanism which they are intended to operate. This coupling comprises a tubular sleeve N, slotted at one end, as at N, to overstand the roll-back M. This sleeve N is 4also slotted at the opposite end, as at N2, to receive a pin O, carried by the knob-shank H".

N3 is a transverse slot in the sleeve N, into which the edge of the dogging-slide F may project slightly and so as to stand in the path of rotation of the arms on the roll-backs J J.

From the foregoing it will be seen that the plate A and knob H may be moved toward or from the plate A and knob H without disconnecting the knob-shank H3 from the sleeve N. This is permitted by the long slot N2, in which the pin O moves. In this connection it should be stated that the presence of the edge of the dogging-slide F serves to prevent longitudinal movement of the sleeve N while this adjustment is being el'l'ected. On the spindle I is placed a washer I), and on the inner side o1c the sleeve N we provide one or more projections, as at N4, which serve to bear against the washer P and hold the spindle I in place.

To remove the sleeve N, it is merely necessary to rotate the knob H slightly to retract the latch-slide B, which in turn carries back the dogging-slide F, so as to free it from the notch N3, whereupon the sleeve N may be readily withdrawn. In this special arrangement the knobs H H rotate depend ently when coupled, and when the dogging-slide F is moved to the locking position it is obvious that both of said knobs are held against rotation, because the latch-slide B cannot be retracted. The knob-shank H is preferably of such length as to allow for the necessary adjustment. The hub of' the cylinder-lock carried in the knob H is also of suflicient length, as shown in dotted lines, Fig. l, so that it will in turn permit of the intended adjustment by allowing a sul'licient telescopic action between said hub and the spindle I. If desired, a screw R2 may be employed to hold the face-plate C tightly against the edge of the door.

In the preferred form the free end of the spring E bears on one side or the other of a high point F2 on the dogging-slide F, whereby the latter will be irictionally held in either of In this respect the spring E performs a double -function--to wit, that ol' advancing slide B in addition to the one last mentioned.

In applying the lock to a door it is merely necessary to bore holes to receive the clamping-screws R R and the coupling N and saw out a small notch at the edge to receive the end plate C and side ribs C C.`
